The PGT subcontrol register contains bits to specify subevents for CYCLES_PGT_STATE (time spent in
open or closed state) and PGT_PAGE_EV (op2cls or cls2opn transitions) as well as provide bits to
further breakdown throttling events into ranks.

The PLD subcontrol register contains bits to specify subevents for PLD_DRAM_EV (by DRAM CMD type),
PLD_RETRY_EV (to specify FVID).
